The smallest price difference between the two lunches is found in the

beverage.
main course.
dessert.
side dish.

Answer 1

To find the smallest price difference between the two lunches, we can compare the costs of each individual item:

• Main course:

  • Current lunch = $1.15
  • Healthier lunch = $1.85
  • Price difference = $1.85 - $1.15 = $0.70

• Side dish:

  • Current lunch = $0.30
  • Healthier lunch = $0.90
  • Price difference = $0.90 - $0.30 = $0.60

• Dessert:

  • Current lunch = $0.30
  • Healthier lunch = $0.10
  • Price difference = $0.30 - $0.10 = $0.20

• Beverage:

  • Current lunch = $0.30
  • Healthier lunch = $0.05
  • Price difference = $0.30 - $0.05 = $0.25

Now we can summarize the price differences:

• Main course: $0.70
• Side dish: $0.60
• Dessert: $0.20
• Beverage: $0.25

The smallest price difference is found in the dessert, with a difference of $0.20.
